Description

A medium-sized rechargeable battery pack for your Raspberry Pi (or Arduino, or Propeller, or anything else that uses 5V!). This pack is intended for providing a lot of power to an iPhone, cell phone, tablet, etc but they found it does a really good job of powering other miniature computers and micro-controllers. If you want even more power, they have a 10,000mAh power pack with two USB ports that can provide up to 2A! Adafruit tested it with an iPhone 5 & 5s so they know it will charge those models. It isn't good for charging large tablets that need 2A charging current such as the iPad.

Inside is a 4000mAh lithium ion battery, a charging circuit (you charge it via the USB cable attached), and a boost converters that provides 5VDC up to 1 Amp via a USB A port. The 1 Amp output is key for when you want to power the Pi, wifi adapters, maybe even small displays. Adafruit hooked it up to a 2.5" NTSC display (powered from the Pi's 5V breakout lines), wireless keyboard/mouse and a small WiFi dongle and it hummed along just fine as a mini computing setup!

The charging circuit will draw 1A from a 5V supply (plug a microUSB connector into the pack and then to a computer or wall adapter). You can charge and power something at the same time but there's ~80% efficiency loss on both ends so if you charge it at 1A and draw 1A at the same time, the battery pack will eventually go empty. However, if you're powering something thats 500mA or less, you can keep it topped up no problem. Also, when you start and stop charging the pack, it will flicker the output, this can cause a 'power sensitive' device like the Pi or an iPhone to reset on the power supply. If using it with a low current load, say under 100mA, the pack may 'fall asleep' - you can use this circuit to keep the pack awake

How long it will last depends a bit on what you have connected. Adafruit ran a 'headless' pi (no keyboard, mouse, display attached) with a mini WiFi adapter plugged into the USB port and pinged it once a second to keep the network connection from going to sleep and it lasted 7 hours. There is a 4-step LED charge status display which you can turn on/off with the button. However, the button is not a general on/off for the entire pack! There's no way to turn off the pack, as long as something is plugged in, it will power it.

Comes with the battery pack and a micro-B cable that you can use for charging the pack or powering a device with a micro B port.
